External mastic in Glenfarg from a team with over 20 years’ experience. 180+ five-star Google reviews and a 4.9 rating.
- Rain getting behind render or cladding at a joint
- Weeds or debris growing in open joints
- Leaking joints around cladding and façade panels
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Point out the joints to other trades
- Fix overflowing gutters above sealed joints
- Check external joints each spring
- Keep movement joints as flexible joints, not mortar
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
External mastic in Glenfarg, done properly
For buildings in Glenfarg, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you have failed seals between different materials and leaking joints around cladding and façade panels, we can help, on façade panels, copings & trims and joints between brick and frames alike.
In and around a place like Glenfarg, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.

Common questions in Glenfarg
Is Glenfarg in your area for external mastic?
Yes. Our work covers the whole of Scotland, and Glenfarg is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Will you come out to Glenfarg?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
How long does the job take?
Most jobs take a few hours to a few days, depending on the length of joint and the access. Your quote will say how long we expect yours to take.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
How do you reach high-level joints?
It depends on the building. Send us pictures and a rough idea of the height.
Common problems we fix in Glenfarg
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that has lost its bond to the brick or render
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
Around Glenfarg, as everywhere, external mastic is only as good as the preparation behind it.
What your quote should include
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
- Whether the sealant suits the joint
- How long to leave it before use
How it works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Outside jobs in Glenfarg need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints

Advice
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Doing several joints on one visit is normally more efficient than separate visits. We will give you a clear price for the lot.

External mastic in Glenfarg: local notes
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Homes close to Arngask Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
